The single-window Model Run Environment

Controlling a simulation and displaying results is performed within the Model Run Environment (MRE). The single-window MRE provides flexible self-contained access to all the controls needed to perform a simulation and to display the results.

It is divided into a number of sections. In the upper left corner is the "Run Control". In the lower left corner is a tabbed panel containing the model "Explorer". On the right hand side are four notebook pages, which can each contain one or more "helpers". Helpers are used to display the behaviour of a model whilst it is running, for example, a graph of a variable, or a data table. Helpers are also used to provide data for the model, for example, using "Input sliders".

To add a helper to a page, select the required helper from the "Add" menu. The two most commonly used helpers can be selected using these buttons on the tool bar:

the plotter; and

the data table;

The pages can be divided vertically or horizontally, to allow more than one helper to be display on each page, and pages can be added or removed. Once one or more helpers have been added to the pages, and are arranged as you wish, the configuration can be saved to a file, for use the next time the same model is built.

To save the current configuration of helpers, chose the "Save configuration…" item on the "File" menu, or use the save button on the tool bar.
To load a previously saved configuration of helpers, chose the "Load configuration…" item on the "File" menu, or use the open button on the tool bar.
A new configuration can be selected, to remove all the currently displayed helpers.
